"As we prepare to move a number of counties from red to yellow, we need all Pennsylvanians to continue to follow the social distancing and mitigation efforts in place," Secretary of Health Dr. Rachel Levine said. "We must continue to protect our most vulnerable Pennsylvanians, which includes our seniors, those with underlying health issues, our healthcare workers and our first responders. I am proud of the work that Pennsylvanians have done so far, but we cannot stop now, we must continue to take the necessary steps to protect ourselves from COVID-19."
